What are the categories of bodies in the solar system? In general, where can they be found?

• Planets found closer are gas planets so they weren't really pulled by the sun's gravity. And the planets farther to the sun are rocky so they were pulled by gravity a lot more.

• Stars found farther out are gas planets so they weren't really pulled by the sun's gravity. And the stars closer to the sun are rocky so they were pulled by gravity a lot more.

• Planets found farther out are gas planets so they weren't really pulled by the sun's gravity. And the planets closer to the sun are rocky so they were pulled by gravity a lot more.
